How do I use the same database in the worker container with pytest-django?

[suspiciousRaccoon]

If I add the following test to the django example:

def test_count_widgets_with_created_widgets(db, celery_setup):
    Widget.objects.create(name="n1")
    Widget.objects.create(name="n2")
    assert count_widgets.delay().get() == 2

it always fails:

assert 0 == 2

After testing a bit this is because the database used in the tasks is different than the one that pytest-django provides via fixture.

How can I make sure the database used in the worker is the same?
